Study finds role of mid-brain in integrating heart and respiratory response to exercise
For almost one hundred years the brain’s “central command” system – whose charge includes controlling the body’s cardiorespiratory response to exercise – has been pursued. Animal experiments and functional imaging studies have provided clues to the location of this system, but the underlying electrophysiological activity has never been measured. Oxford University researchers recently examined several deep brain nuclei during exercise and have concluded that the periaqueductal grey area (PAG), the small-celled gray matter adjoining or surrounding the cerebral aqueduct and the third ventricle in the midbrain, contains the greatest number of neural changes in connection with anticipation of exercise. more
Correlation between bile duct obstruction and ductal cancer found
When bile duct cancer cells were placed in the liver of animals with bile duct obstruction, they grew more rapidly than identical cells placed in animals without bile duct obstruction. In fact, half of the total liver mass of the rats with bile duct obstruction became replaced by cancer cells within three weeks compared to only 16 percent of that of animals without bile duct obstruction. more
A better blood test for prostate cancer
New studies of a blood protein recently identified at Johns Hopkins, early prostate cancer antigen-2 (EPCA-2), may change the way men are screened for prostate cancer - a disease that kills tens of thousands of men every year. more
